UNITED STATES PATENT OFFICE. A

RANSOM G. WRIGHT, OF PHILADELPHIA, PENNSYLVANIA, AND FRANK E. STEBBINS, OF WASHINGTON, DISTRICT OF COLUMBIA.

CONSTRUCTION OF CAR-TRUCKS.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed Oct0ber4,1902, fierial No. 125,890. Renewed October 18, 1904. Serial No. 228,926.

To all whom it may concern:

Be it known that we, RANSOM O. WRIGHT and FRANK E. S'rnnBINs, citizens of the United States, residing, respectively, at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and at Washington, District of Columbia, have invented certain new and useful Improvements in the Construction of Car-Trucks, of which the following is a specification.

The object of our invention is the production of a car truck frame which can easily and cheaply be constructed and repaired in the ordinary car shop without the use of special tools, machinery, or appliances; which shall have a transom adapted to support great weights; and which shall have pedestals that can be detached when worn or injured and others substituted therefor.

With these main ends in view our invention consists in certain novelties of construction and combinations of parts hereinafter set forth and claimed.

The accompanying drawings illustrate one complete example and one modification of the physical embodiment of our invention constructed according to the best modes we have so far devised for the practical application of the principle.

Figure 1 is a side view in elevation of the truck frame with wheels, journal boxes, and springs in place above the journal boxes. Fig. 2 is a half top plan view of Fig. 1 showing the method of strengthening the transom. Fig. 3 is a section of Fig. 1 on line .t.t through the pedestal neck and side beams. Fig. 4 is a section of Fig. 1 on line rv. Fig. 5 is a side view in elevation of a modification. Fig. 6 is a partial top plan view of Fig. 5. Fig. 7 is a section of Fig. (3 taken in a line between the transoms.

Referring to the figures of the drawings, the numeral 1 designates the outside flanged beam of the frame; 2, the inside flanged beam; 3, 3, the transom beams, also flanged; 4, 4, connection angles which serve by means of rivets to secure the ends of the transoms to the inside fianged beams; 5, bottom stiffening plates which are riveted to the lower flanges of the transoms at the ends and to the flanges of the side pieces; 6, cast metal pedestals; 7 the pockets for the springs; 8, pedestal necks; 9, the top flanges of the necks; 10, the bottom flanges of the necks; 11, the webs of the necks, located between the top and bottom flanges; 12, the top perpendicular flanges over or adjacent the spring pockets; 12, bottom flanges; 13, rivets which secure the webs of the pedestals and the ends of the outside and inside flanged beams; and 14 are rivets through the flanges of the neck at the top and bottom thereof and the flanges of the beams.

in the example illustrated by Figs. 1, 2, 3, and 4 l the numeral 15 designates a channel beam extending from side to side of the frame; 16, rivets seeming the channel beam to the transom beams, said rivets being passed through the web of the channel beam and the top flanges of the transom beams; 17, rivets securing the channel beam to the top flanges of the outside and inside flanged beams which constitute a side; 18, a hole in the channel beam; 19 wheels and axles; 20, the journals; 21, the spiral springs resting upon the journal boxes and bearing against the bottoms of the pockets in the pedestals; and 22, are the journal boxes.

Referring to Figs. 5, 6, and 7, the numeral 35 designates the widened top flange of the inside flanged beams; 36, rivets securing the ends of the transoms to the flange; 37, filling pieces hooking over the outer and inner side pieces, as shown in Fig. 7, so as to take the shearing strains off the rivets; and 38 are rivets through the filling pieces and inner and outer flanged beams.

Referring to both examples, 39 designates the strengthening flanges of the outer pedestal legs or jaws; 40, spacing thimbles; 41, tie bolts; 42, nuts on the bolts; 43, the outer and inner bearing flanges of the jaws which engage recesses in the vertical sides of the journal boxes; and 43 in Fig. l are the bearings on flanges 12 for the heads of the bolts.

The methods of assembling the several parts of the frames, as illustrated, will readily be understood from an inspection of the drawings and, therefore, need not be specifically described.

From the foregoing description taken in connection with the drawings it is obvious that We have produced car truck frames which fulfil all the conditions set forth as the end and object of our invention.

In physically embodying our improvements, it is, of course, to be understood that modified modes of construction in details may be adopted and followed without constituting substantial departures.
